Capillary electrophoresis–mass spectrometry

Capillary electrophoresis–mass spectrometry (CEMS) is an analytical chemistry technique formed by the combination of the liquid separation process of capillary electrophoresis with mass spectrometry.[1] Ions are typically formed by electrospray ionization,[2] but they can also be formed by matrix-assisted laser desorption/ionization[3] or other ionization techniques. It has applications in basic research in proteomics[4] and quantitative analysis of biomolecules[5] as well as in clinical medicine.[6][7]

The original interface between capillary zone electrophoresis and mass spectrometry was developed in the mid-1980s by Richard D. Smith and coworkers at Pacific Northwest National Laboratory, and who also later were involved in development of interfaces with other CE variants, including capillary isotachophoresis and capillary isoelectric focusing.
